An Introduction to Calcium Dosage
The recommended dose of
calcium depends on several different factors, such as:
- Your age
- The reason you take calcium
- The type of calcium you take
- How much calcium you get through foods
- Other medical conditions you may have.
As always, do not adjust your dosage without your healthcare provider's approval.

The recommended Adequate Intake for pregnant or breastfeeding women is the same as for non-pregnant individuals.
For nutrients that can cause toxicity, a "Tolerable Upper Intake Level" (UL) is given. This is the maximum that can be taken (from all sources, including the diet) without causing significant toxicity. The UL of calcium for infants up to 12 months old has not been established. For everyone else, the UL is 2500 mg (2.5 grams) daily.
